iPhone 17 Pro Bluetooth audio stuttering with JBL Tuner 3 speaker
Dear Apple support team,
I am experiencing persistent Bluetooth audio stuttering when using my iPhone 17 Pro with a JBL Tuner 3 speaker.
The issue has been present since the very first connection. Audio frequently stutters or briefly cuts out during playback, even when the iPhone is stationary with its screen locked.
Device information:
- Phone: Apple iPhone 17 Pro
- iOS version: 27.2 (previously 27.0.1)
- Speaker: JBL Tuner 3 (latest firmware installed)
Troubleshooting already performed:
- Updated iOS from 27.0.1 to 27.2 – no improvement.
- Updated JBL Tuner 3 firmware.
- Removed and re-established Bluetooth pairing.
- Reset the JBL Tuner 3 to factory settings.
- Tested with Wi-Fi disabled and devices placed close together.
Comparison tests:
- iPhone 17 Pro + JBL Tuner 3: Audio stuttering.
- iPhone 13 Pro + JBL Tuner 3: Works perfectly.
- iPhone 17 Pro + JBL Charge 4: Works perfectly.
These results suggest a compatibility issue specific to the iPhone 17 Pro and JBL Tuner 3 combination.
Could you please investigate whether this is a known Bluetooth compatibility issue and advise if a software or firmware fix is available or planned?
I would appreciate a technical response from both Apple and JBL, rather than general Bluetooth troubleshooting instructions, as the standard troubleshooting steps have already been completed.
Thank you for your assistance.
iPhone 17 Pro, iOS 27
